Cubase 10 hanging during audio mixdown export

Cubase version 10.0.30

I’ve never had this before but it’s happened a few times now in the last few days. I wondered if anyone had experienced the same behaviour.

During audio mixdown export it will go through for a while and then stop - it doesn’t actually crash but the beachball of doom appears and Activity Monitor says Cubase not responding…

After a couple of restarts and retries for the export it seems to still work, but damned annoying. And very time consuming.

Yes they’re very large projects and tethered to Vienna Ensemble Pro (which doesn’t hang or crash) - but as I say, I’ve really never has this happen in the past.

Mac OS is 10.13.5 and VEPro is 7.0.889

I had to go to my audio interface and increase the buffer settings

I used to use Cubase 8.5 before I went to Cubase 10 and could easily work down to 32 samples (RM FF800) those days are long gone since I went to C10
